SPUTUlVI-RECEIVER.

Application filed April 2, 1915, Serial No. 18,659.

To all whom it may concern:

Be it known that I, FERDINAND TVIijl-IL- BAOH, a subject of the Emperor of Austria Hungary, and a resident of New York, in the county of New York and State of New York, have invented certain new and use ful Improvements in Sputum-Receivers, of which the following is a specification.

This invention relates to a sputum container, which is attached to an article of furniture, such as a chair or table, properly protected and provided with means for bringing it into operative position for use.

The invention consists of a sputum container operated by means of a handle, and supported, for instance, by a chair, so that the container is held under its seat when not in use, and brought into operative position when required.

Referring to the drawings Figure 1 is a front elevation of a chair showing the application of the invention.

Fig. 2 is a vertical sectional view, taken on line 22 of Fig. 1.

Fig. 3 is a bottom plan view of the same.

Fig. 4 is another vertical sectional view, taken on line H of Fig. 1, and

Fig. 5 is an enlarged sectional view showing in detail the handle arrangement.

The chair shown in the drawing is comprised of side frames 13 and 1 1, to the former of which is attached a side plate 10, by means of the bolt 12 passing through a slot formed therein, and having a front extension 15, carrying a pin 16, engaged by a bell-crank lever 17, pivoted at 18, to the side member 13 of the chair.

The movement of the bell-crank lever is controlled by a return spring 19 secured to the pivot 18 of the bell-crank, one end of the spring resting against a pin in the bellcrank, and the other against a support pin 21, fixed in the side frame 13 of the chair, the bell-crank being operated by the rod 23 provided with a handle 25.

The device as illustrated provides a sanitary means for receiving sputum and consists of a web or tape 27, of absorbent material, such as a textile fabric, held on the roller 28 secured to a part of the chair; the free end of the web is fastened to the roller 29, the shaft of which extends through the walls of the receiver casing, and carries a Specification of LettersPatent.

Renewed January 18, 1917. Serial No. 143,187.

pulley 30, intermittently moved by means of a belt 31, from a pulley 32, on a shaft 33,

having its bearings in a casing 31, secured to the movable frame.

The shaft 33 is provided with a disk 24 and a pinion 35. The pinion engages with a stationary rack 36, secured to the lower side of the chair seat 11. The shaft is longitudinally movable in its bearings and its outer end bears against a flat spring 37, secured to the lower side of the chair seat 11. A blade spring 38, having a bent portion 39, is adapted to'cooperate with the disk 24:: for causing the movement of the shaft 33 in one direction, while the contact of the end of the shaft 33, with the spring 37, moves the shaft in the opposite direction.

For the purpose of conveniently placing the handle 25, so as not to obstruct the surface of the seat, the latter may be provided with a recess 40, as shown in Fig. 5 into which the handle 25 may be placed when the container is not in use.

The operation of the device illustrated consists in pulling the handle 25, whereby the bell-crank 17 is caused to turn on its pivot to move the sputum receiver casing 46, so that the same extends in front of the seat. After using the container, the handle 25 is released, returning the container again into its normal position.

When the sputum container is moved into operative position, and due to the fact that the pinion 35 is now immovable and not in mesh with the rack 36, a length of web is pulled from its roller and the movement of the receiver causes contact between the disk 24 and the end 39 of the spring 38, whereby the shaft 33 is moved and the pinion 35 brought into engagement with the rack 36. On the return movement of the receiver, due to the action of the spring 19, rotation is imparted to the shaft, and consequently, the roller 29 in the receiver rolls up the limited length of the web receiving the sputum, which is then fully covered by an outer layer of the web.

At the return of the frame, the spring 37, pressing against the end of the shaft 33, disengages the pinion 35 from the rack 36 and the entire device is again in its normal position.

Thus it will be seen that the web, when used, can be readily removed without the neweb' of fabric, a second shaft mounted in said frame, means for conveying motion between said shafts, a pinion on said second shaft, a rack adapted to be engaged by said pinion, means for causing engagement of said pinion with said rack when said frame moves in one direction, means for moving said contalner 1n the oppos1te dlrectlon, and

means for causing disengagement of said pinion from said rack when said frame moves in the opposite direction.

2. The combination with a container of means for moving said container in one direction into an operative position, means for returning said container into an inoperative position, and a roller in said container for holding a web of fabric said roller being adapted to rotate when said container moves into its inoperative position.

Signed at New York, in the county of New York and State of New York this ninth day of March A. D. 1915.
